Discover the power of the Trowel Variables

The key feature of Trowel is its variables. The Trowel variables allow you to define several values depending of criteria like a pseudo-class, a modifier class, a responsive breakpoint, etc. This pattern allows the user to totally control the CSS output, by generating only the style required. CSS frameworks will no more be big boats, they will just fit for you website.

$button--color: rgb(0, 0, 0) !default;

$button--background-color: (
  'default': rgb(255, 255, 255),
  ':hover': rgb(225, 225, 225),
  '-primary': (
    'default': rgb(31, 13, 51),
    ':hover': rgb(21, 3, 41),
  ),
) !default;

$button--cursor: (
  '<button': default,
) !default;

$button--selector: selector(new 'btn');

@include statement($button--selector, (
  ('display', inline-block),
  ('color', $button--color),
  ('background-color', $button--background-color),
  ('cursor', $button--cursor),
  ('opacity', $button--opacity),
));
.btn {
  display: inline-block;
  color: rgb(0, 0, 0);
  background-color: rgb(255, 255, 255);
}

.btn:hover {
  background-color: rgb(225, 225, 225);
}

.btn--primary {
  background-color: rgb(31, 13, 51);
}

.btn--primary:hover {
  background-color: rgb(21, 3, 41);
}
